            <p>Some plot types have additional color handling to facilitate easier handling and

                            <p>Pie plots support the concept of color-themes. A color theme is
                                simple a set of colors used for consecutive slices within the Pie.
                                How to specify color-themes is further discussed in <a class="xref" href="ch16.html#sec.pie-color-themes" title="Specifying slice colors and using themes">Specifying slice colors and using themes</a>.</p>

                                have the concept of color maps. This is a range of colors used to
                                indicate the data in the plot. Examples of color maps can be found
